EXTENDED MOBILITY TYRE COMPRISING BEAD WITH SYMMETRICAL FORCE DISTRIBUTION

摘要

The invention relates to a tyre for a vehicle wheel. The inventive tyre consists of two sidewalls, beads comprising a seat and an outer flange which are intended to come into contact with an adapted rim and a reinforcing structure (2). Moreover, at least one of the aforementioned beads comprises an essentially-circumferential wire structure which is divided into two zones, one (30) of which is used to anchor the reinforcing structure in the bead. Said anchoring zone (30) comprises circumferential wires which are arranged such that they are essentially adjacent to a portion (21) of the reinforcing structure and at least two stacks which are distributed on either side of said reinforcing structure, a binding mixture being disposed between the circumferential wires and the reinforcing structure. Moreover, said anchoring zone is arranged in the bead such that, at nominal pressure, the tensile stresses from the reinforcing structure are distributed essentially uniformly along the length of the contact zone.
